It fits the Legion 5 Pro 16IAH7H, 16ARH7H, Legion 5 15IAH7H, and over 140 additional Legion variants sharing the same power rail and connector. OEM part numbers covered include 5B11F24156, 5B11F24161, L21C4PC1, L21D4PC1, and L21M4PC3.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLegion 5 and 5 Pro series fit:\u003c\/strong\u003e\n    These models share a common 15.44V four-cell Li-Polymer architecture, the same ZIF connector pinout, and a unified BMS handshake protocol. Any variant in this family running the same voltage rail accepts this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on a Legion 5 Pro chassis. The BMS negotiated correctly, charge termination triggered at full capacity, and no fault codes appeared on either the EC or BIOS battery page.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLegion BIOS learn cycle after swap:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on battery alone, then charge uninterrupted to 100%. This resets the BIOS learn cycle against the new cell chemistry and clears the false \"poor health\" or inaccurate capacity warning that appears after every cell replacement on Legion hardware.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLegion shutting down at 20–30% shown after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder full CPU and discrete GPU load, the Legion platform draws hard on the battery. A freshly fitted cell has an uncalibrated fuel gauge IC, so the reported state-of-charge does not match actual cell voltage. When real voltage hits the EC's low-voltage cutoff threshold — around 13.5V under load — the system shuts down even though the gauge still shows 20–30%. Two full discharge-to-hibernate and uninterrupted recharge cycles recalibrate the gauge IC and align the reported percentage with true cell voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery Wh as wrong after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure the BIOS displays is read from EEPROM data embedded in the battery's BMS, not calculated live from the cell. A replacement cell may carry EEPROM values from a slightly different production batch, causing the system info page to show a Wh rating that does not match the label. This is a data field mismatch, not a capacity fault. The actual usable energy the cell delivers is unchanged — the displayed figure is cosmetic and does not affect charging or discharge behaviour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409542119514,"sku":"BWCS-LVN516NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409542152282,"sku":"BWCS-LVN516NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409542185050,"sku":"BWCS-LVN516NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVN516NB-1.webp?v=1779579986","url":"https:\/\/batteryweb.com\/products\/lenovo-legion-5-pro-16iah7h-82rf005pid-replacement-battery-1544v-5100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
